BACKGROUND OF THE INVENTION

1. Field of the invention

The present invention relates to a sewing method for a wrinkle-free shirt. More particularly, the present invention relates to a sewing method for a wrinkle-free shirt, in which a fabric core made of cotton and/or an adhesive film is attached to an end part of an outer shell of a shirt such that it can be sewed together with the outer shell of the shirt, thereby preventing the shirt from wrinkling.

2. Description of the Prior Art

As generally known in the art, a sewing technique is a basic and essential technique in the garment industry. However, a wrinkling phenomenon occurring at seam lines of a garment has long plagued the garment industry. Such a wrinkling phenomenon is typically caused by thread shrinkage, which occurs during laundering of the garment.

In order to solve the wrinkling phenomenon occurring at seam lines of the garment, Jong Wong has filed a plurality of Patent Applications with USPTO. The above Patent Applications are now allowed to Jong Wong with U.S. Pat. Nos. 5,568,779 (issued on Oct. 29, 1996), 5,590,615 (issued on Jan. 7, 1997), 5,713,292 (issued on Feb. 3, 1998), 5,775,394 (issued on Jul. 7, 1998), and 5,782,191 (issued on Jul. 21, 1998). These Patents disclose a sewing method for preventing components of a garment, such as shoulder seam lines, lateral seam lines, a chest pocket and sleeves, from wrinkling. According to the sewing method disclosed in the above Jong Wong's Patents, a plastic bonding tape, which is made from a thermally adhesive bonding material, is placed along the seam lines such that the plastic bonding tape can be sewed together with the seam lines.

Therefore, the seam lines of the garment can be securely fastened by means of the plastic bonding tape even if thread shrinkage occurs in the garment after laundering of the garment, thereby preventing the garment from wrinkling.

However, since the sewing method disclosed in the above Patents uses the plastic adhesive tape, it is necessary to apply heat to the surface of the plastic adhesive tape for a long time in order to melt the plastic adhesive tape. In addition, the above Patents present disadvantages in that they require the special process and equipment for melting the plastic adhesive tape.

In addition, since the plastic adhesive tape used in the above sewing method is made from a thermoplastic material, the hardness of the plastic adhesive tape may rise after it has been cooled, so that the plastic adhesive tape has superior strength and inferior flexibility, causing the plastic adhesive tape to be easily broken. Furthermore, the plastic adhesive tape may stimulate a skin of a user wearing the garment, thereby degrading wearing comport.

SUMMARY OF THE INVENTION

Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a sewing method for a wrinkle-free shirt, which can easily bond an adhesive tape to seam lines through simple pressing work while applying heat to the adhesive tape for a short time and can provide superior wearing comport and adhesive characteristics at seam lines as compared with those of the prior art.

In order to accomplish this object, the present invention provides a sewing method for a shirt capable of preventing the shirt from wrinkling, the shirt including a front panel, a rear panel sewed with the front panel, and sleeves formed at both sides of the shirt corresponding to arms of a user, in which a central button placket is provided at a central portion of the front panel, the central button placket has a plurality of holes, which are longitudinally incised so as to allow the user to easily wear or take off the shirt using buttons, a collar is provided above the center placket corresponding to a neck of the user, a pocket is provided at one side or both sides of a chest part of the front panel, a yoke extends from an upper part of the rear panel to a shoulder line, a cuff is provided at a lower end part of each sleeve corresponding to a wrist of the user, and a sleeve placket formed at an upper part of the cuff lengthwise along the sleeve, wherein seam lines are provided to connect components of the shirt and the seam lines include a pocket seam formed at the chest part of the front panel, a collar seam formed at a neck part of the shirt, a cuff seam formed at the wrist part of the shirt provided at the lower portion of the sleeve, a side seam connecting the front panel with the rear panel, a shoulder seam formed at a shoulder part of the shirt, a sleeve seam connecting the shoulder part of the shirt with the sleeve, a sleeve placket seam formed at an upper portion of the cuff, and a yoke seam formed at the yoke provided at the upper portion of the rear panel, in which the sleeve placket seam is divided into an upper sleeve placket seam and a lower sleeve placket seam, and the yoke seam is divided into a side yoke seam which is sewed to the sleeve at both lateral sides of the yoke and a lower yoke seam which is sewed to the upper portion of the rear panel at a lower end of the yoke, the method comprising the steps of: attaching a fabric core and/or an adhesive film to each seam; and sewing the fabric core and/or the adhesive film with each seam.

According to the sewing method of the present invention, the adhesive film and/or the fabric core is attached to and sewed with to the seam part of the shirt at a relevant temperature condition through simple pressing work, without requiring a long heating process, thereby simplifying the fabrication processes for the shirt. In addition, since the present invention employs the fabric core and/or the adhesive film having superior flexibility, the wearing comfort may be improved as compared with the prior art employing the plastic adhesive tape.

A central button placket 5 is provided at the central portion of the front panel 1. The central button placket 5 has a plurality of holes, which are longitudinally incised so as to allow a user to easily wear or take off the shirt using buttons 4. A pocket 6 is provided at one side or both sides of a chest part of the front panel 1. A “neckband” provided at an upper end portion of the shirt is called a “collar” 7. In addition, a portion of the shirt extending from an upper part of the rear panel 2 to a shoulder line is called a “yoke” 8 and a portion of the shirt provided at a lower end part of the sleeve 3 is called a “cuff” 9. Furthermore, an incised portion formed at an upper part of the cuff 9 lengthwise along the sleeve 3 is called a “sleeve placket” 10.

Referring to FIGS. 1 to 4, seam lines are provided to connect components of the shirt. The seam lines include a pocket seam A formed at the chest part of the front panel 1, a collar seam B formed at the neck part of the shirt, a cuff seam C formed at the wrist part of the shirt provided at a lower portion of the sleeve 3, a side seam D connecting the front panel 1 with the rear panel 2, a shoulder seam E formed at the shoulder part of the shirt, a sleeve seam F connecting the shoulder part of the shirt with the sleeve 3, a sleeve placket seam G formed at an upper portion of the cuff, and a yoke seam H formed at the yoke 8 provided at the upper portion of the rear panel 2.

As shown in FIG. 2, the cuff 9 is fastened by means of a button 10. The sleeve placket seam G provided at the upper portion of the cuff 9 is divided into an upper sleeve placket seam G₁ and a lower sleeve placket seam G₂. In addition, as shown in FIGS. 3 and 4, the yoke seam H is divided into a side yoke seam H₁ which is sewed with the sleeve 3 at both lateral sides of the yoke 8 and a lower yoke seam H₂ which is sewed with the upper portion of the rear panel 2 at a lower end of the yoke 8.

According to the sewing method of the present invention, a core made of a fabric, such as cotton, (hereinafter, referred to as a fabric core) and/or a film having an adhesive property (hereinafter, referred to as an adhesive film) is attached to and sewed with the seam lines of the shirt having the above structure, thereby preventing the shirt from wrinkling.

Hereinafter, the sewing procedure for each seam line shown in FIGS. 1 to 4 according to the present invention will be described with reference to FIGS. 5 to 13.

FIGS. 5 a and 5 b are views illustrating the pocket seam A before and after sewing work, respectively.

The pocket 6 is fixedly sewed to a front surface of the front panel 1. According to the present invention, as shown in FIG. 5 a, the adhesive film m is attached to both inner side end portions of the pocket 6. In addition, as shown in FIG. 5 b, both side end portions of the pocket 6 are folded together with the adhesive film m, so that the side end portions of the pocket 6 are bonded with the adhesive film m. In this state, sewing work is performed with respect to both side end portions of the pocket 6 (see, seam lines “s”). After that, the adhesive film m is pressed by means of a press device while applying heat having a predetermined temperature to the adhesive film m, so that the adhesive film m is completely bonded to the end portions of the pocket 6, thereby obtaining the pocket seam A as shown in FIG. 1. For instance, in the case of the pocket seam A, the heating temperature is 135° C., pressing pressure is 5 kg/cm², heating and pressing time is about 12 seconds, and the adhesive film m has a width of about 6 mm. However, the fabrication condition for the pocket seam A may not be limited to the above condition, but may be variously selected depending on quality and characteristics of texture of the garment.

FIGS. 6 a and 6 b are views illustrating the collar seam B before and after sewing work, respectively.

The collar 7 is fixedly sewed to the upper portion of the shirt. As shown in FIG. 6 a, the fabric core p is placed at an inner end portion of an outer shell 7 a of the collar 7 and the adhesive film m is attached to the other surface of the fabric core p such that a predetermined portion of the adhesive film m extends beyond an end portion of the fabric core p while facing the outer shell 7 a of the collar 7. In this state, the end portion of the outer shell 7 a of the collar 7 is folded together with the adhesive film m such that the end portion of the outer shell 7 a of the collar 7 can be bonded with the adhesive film m. That is, predetermined portions of the adhesive film m and the outer shell 7 a of the collar 7, which extend beyond the end portion of the fabric core p, are folded together so that the predetermined portion of the outer shell 7 a of the collar 7 is bonded to the adhesive film m attached to the other surface of the fabric core p. After that, an end portion of an inner shell 7 b of the collar 7 is folded corresponding to the end portion of the outer shell 7 a of the collar 7. Then, sewing work is performed with respect to the end portions of the outer shell 7 a and inner shell 7 b of the collar 7 (see, seam line “s”). After that, the adhesive film m is pressed by means of a press device while applying heat having a predetermined temperature to the adhesive film m, so that the adhesive film m is completely bonded to the end portion of the outer shell 7 a of the collar 7, thereby obtaining the color seam B as shown in FIG. 1. For instance, in the case of the color seam B, the heating temperature is 140° C., pressing pressure is 5 kg/cm², heating and pressing time is about 9 seconds, and the adhesive film m has a width of about 12 mm. However, the fabrication condition for the color seam B may not be limited to the above condition, but may be variously selected depending on quality and characteristics of texture of the garment.

The cuff 9 is fixedly sewed to the wrist part of the shirt provided at a lower portion of the sleeve 3. As shown in FIG. 7 a, the fabric core p is placed at an inner end portion of an outer shell 9 a of the cuff 9 and the adhesive film m is attached to the other surface of the fabric core p such that a predetermined portion of the adhesive film m extends beyond an end portion of the fabric core p while facing the outer shell 9 a of the cuff 9. In this state, the end portion of the outer shell 9 a of the cuff 9 is folded together with the adhesive film m such that the end portion of the outer shell 9 a of the cuff 9 can be bonded with the adhesive film m. That is, predetermined portions of the adhesive film m and the outer shell 9 a of the cuff 9, which extend beyond the end portion of the fabric core p, are folded together so that the predetermined portion of the outer shell 9 a of the cuff 9 is bonded to the adhesive film m attached to the other surface of the fabric core p. After that, an end portion of an inner shell 9 b of the cuff 9 is folded corresponding to the end portion of the outer shell 9 a of the cuff 9. Then, sewing work is performed with respect to the end portions of the outer shell 9 a and inner shell 9 b of the cuff 9 (see, seam line “s”). After that, the adhesive film m is pressed by means of a press device while applying heat having a predetermined temperature to the adhesive film m, so that the adhesive film m is completely bonded to the end portion of the outer shell 9 a of the cuff 9, thereby obtaining the cuff seam C as shown in FIG. 1. For instance, in the case of the cuff seam C, the heating temperature is 135° C., pressing pressure is 5 kg/cm², heating and pressing time is about 12 seconds, and the adhesive film m has a width of about 12 mm. However, the fabrication condition for the cuff seam C may not be limited to the above condition, but may be variously selected depending on quality and characteristics of texture of the garment.

FIG. 8 is a view illustrating the side seam D, which has been obtained when the front panel 1 is sewed with the rear panel 2. After folding end portions of the front and rear panels 1 and 2, the end portions of the front and rear panels 1 and 2 engage with each other while interposing the adhesive film m therebetween, thereby bonding the end portions of the front and rear panels 1 and 2 to each other. Then, sewing work is performed with respect to the end portions of the front and rear panels 1 and 2 (see, seam lines “s”). After that, the adhesive film m is pressed by means of a press device while applying heat having a predetermined temperature to the adhesive film m, so that the adhesive film m is completely bonded to the front and rear panels 1 and 2, thereby obtaining the side seam D as shown in FIG. 1. For instance, in the case of the side seam D, the heating temperature is 180° C., pressing pressure is 5 kg/cm², heating and pressing time is about 15 seconds, and the adhesive film m has a width of about 6 mm. However, the fabrication condition for the side seam D may not be limited to the above condition, but may be variously selected depending on quality and characteristics of texture of the garment.

As shown in FIG. 9 a, an outer shell 8 a and an inner shell 8 b of the yoke 8 are placed on both surfaces of the front panel 1 and the adhesive film m is attached to an end portion of the outer shell 8 a of the yoke 8. Then, end portions of the outer shell 8 a and the inner shell 8 b of the yoke 8 are folded in a direction opposite to the front panel 1 as shown in FIG. 9 b. Thus, the end portion of the outer shell 8 a of the yoke 8 is folded together with the adhesive film m so that the end portion of the outer shell 8 a of the yoke 8 is bonded to the adhesive film m. In this state, sewing work is performed with respect to the end portions of the outer shell 8 a and inner shell 8 b of the yoke 8 (see, seam lines “s”). After that, the adhesive film m is pressed by means of a press device while applying heat having a predetermined temperature to the adhesive film m, so that the adhesive film m is completely bonded to the end portion of the outer shell 8 a of the yoke 8, thereby obtaining the shoulder seam E as shown in FIG. 1. For instance, in the case of the shoulder seam E, the heating temperature is 120° C., pressing pressure is 5 kg/cm², heating and pressing time is about 12 seconds, and the adhesive film m has a width of about 6 mm. However, the fabrication condition for the shoulder seam E may not be limited to the above condition, but may be variously selected depending on quality and characteristics of texture of the garment.

FIGS. 10 a and 10 b are views illustrating the sleeve seam F before and after sewing work, respectively.

The sleeve 3 extends from a connection part between the front and rear panels 1 and 2 of the shirt. After placing predetermined parts of the front and rear panels 1 and 2 on an inner end portion of the sleeve 3, the end portion of the sleeve 3 extending outward from the end portions of the front and rear panels 1 and 2 is folded. Then, the adhesive film m having a predetermined length is attached to an area ranging from the end portions of the front and rear panels 1 and 2 to the folded end portion of the sleeve 3. In this state, end portions of the front and rear panels 1 and 2 are folded together with the adhesive film m such that the adhesive film m can be bonded with the front and rear panels 1 and 2. In this case, the other sides of the folded end portions of the front and rear panels 1 and 2 are bonded to the folded end portion of the sleeve 3 by means of the adhesive film m. Then, sewing work is performed with respect to the folded end portions of the front and rear panels 1 and 2 and the sleeve 3 as well as the folded end portion of the sleeve 3 and the front and rear panels 1 and 2 (see, seam lines “s”). After that, the adhesive film m is pressed by means of a press device while applying heat having a predetermined temperature to the adhesive film m, so that the adhesive film m is completely bonded to the end portion of the sleeve 3 and the front and rear panels 1 and 2, thereby obtaining the sleeve seam F as shown in FIG. 1. For instance, in the case of the sleeve seam F, the heating temperature is 180° C., pressing pressure is 5 kg/cm², heating and pressing time is about 9 seconds, cooling time is about 4 seconds and the adhesive film m has a width of about 12 mm. However, the fabrication condition for the sleeve seam F may not be limited to the above condition, but may be variously selected depending on quality and characteristics of texture of the garment.

FIG. 11 is a view illustrating the sleeve placket seam G including the upper sleeve placket seam G₁ sewed with the lower sleeve placket seam G₂ shown in FIG. 2.

As shown in FIG. 11, the upper sleeve placket seam G₁ and the lower sleeve placket seam G₂ shown in FIG. 2 can be obtained when upper and lower sleeve placket covers 11 a and 11 b, which cover end portions of upper and lower sleeve placket seams, are folded on end portions of the upper and lower sleeve placket seams. In this case, the adhesive film m is attached to the end portions of the upper and lower sleeve placket covers 11 a and llb, respectively. In addition, the end portions of the upper and lower sleeve placket covers 11 a and 11 b having the adhesive film m are inwardly folded such that they make contact with the end portion of the sleeve 3. Thus, the adhesive film m is folded together with the end portions of the upper and lower sleeve placket covers 11 a and 11 b. Here, the adhesive film m can be completely bonded to the end portions of the upper and lower sleeve placket covers 11 a and 11 b by applying pressure and heat having a predetermined temperature to the adhesive film m by means of a press device. Then, sewing work is performed with respect to the folded end portions of the upper and lower sleeve placket covers 11 a and 11 b and the corresponding end portion of the sleeve 3 (see, seam line “s”), thereby obtaining the sleeve placket seam G as shown in FIG. 1. For instance, in the case of the sleeve placket seam G, the heating temperature is 165° C., pressing pressure is 4 kg/cm², heating and pressing time is about 12 seconds, and the adhesive film m has a width of about 6 mm. However, the fabrication condition for the sleeve placket seam G may not be limited to the above condition, but may be variously selected depending on quality and characteristics of texture of the garment.

FIGS. 12 a and 12 b are views illustrating the side yoke seam H₁ before and after sewing work, respectively.

As shown in FIG. 3, the side yoke seam H₁, is connected to the sleeve 3 at both sides of the yoke 8. According to the present invention, as shown in FIG. 12 a, the adhesive film m is attached to both inner side end portions of the outer shell 8 a of the yoke 8. In addition, as shown in FIG. 12 b, both side end portions of the outer shell 8 a of the yoke 8 are folded together with the adhesive film m, so that the side end portions of the outer shell 8 a of the yoke 8 are bonded with the adhesive film m. In this state, sewing work is performed with respect to both side end portions of the outer shell 8 a of the yoke 8 (see, seam lines “s”). After that, the adhesive film m is pressed by means of a press device while applying heat having a predetermined temperature to the adhesive film m, so that the adhesive film m is completely bonded to the end portion of the outer shell 8 a of the yoke 8, thereby obtaining the side yoke seam H₁ as shown in FIG. 4. For instance, in the case of the side yoke seam H₁, the heating temperature is 180° C., pressing pressure is 5 kg/cm², heating and pressing time is about 15 seconds, and the adhesive film m has a width of about 12 mm. However, the fabrication condition for the side yoke seam H₁ may not be limited to the above condition, but may be variously selected depending on quality and characteristics of texture of the garment.

FIGS. 13 a and 13 b are views illustrating the lower yoke seam H₂ before and after sewing work, respectively. The lower yoke seam H₂ is obtained when the rear panel 2 of the shirt is sewed to the yoke 8. As shown in FIG. 13 a, the outer shell 8 a and the inner shell 8 b of the yoke 8 are attached to both surfaces of the rear panel 2 and the adhesive film m is attached to the end portion of the outer shell 8 a of the yoke 8. After that, as shown in FIG. 13 b, the end portion of the outer shell 8 a of the yoke 9 is folded in a direction opposite to the rear panel 2. Thus, the end portion of the outer shell 8 a of the yoke 8 is folded together with the adhesive film m so that the end portion of the outer shell 8 a of the yoke 8 is bonded to the adhesive film m. In this state, sewing work is performed with respect to the end portions of the outer shell 8 a and inner shell 8 b of the yoke 8 and the end portion of the rear panel 2 (see, seam lines “s”). After that, the adhesive film m is pressed by means of a press device while applying heat having a predetermined temperature to the adhesive film m, so that the adhesive film m is completely bonded to the end portion of the outer shell 8 a of the yoke 8, thereby obtaining the lower yoke seam H₂ as shown in FIG. 4. For instance, in the case of the lower yoke seam H₂, the heating temperature is 180° C., pressing pressure is 5 kg/cm², heating and pressing time is about 15 seconds, and the adhesive film m has a width of about 6 mm. However, the fabrication condition for the lower yoke seam H₂ may not be limited to the above condition, but may be variously selected depending on quality and characteristics of texture of the garment.

As described above, according to the sewing method of the present invention, the fabric core and/or the adhesive film is attached to and sewed with the each seam part of the shirt. In addition, the fabric core and/or the adhesive film is pressed and heated with a predetermined temperature so that the fabric core and/or the adhesive film can be securely bonded to the seam part of the shirt. Accordingly, the sewing method of the present invention can easily bond the adhesive film to the seam part of the shirt at a relevant temperature condition through simple pressing work, without requiring a long heating process, thereby simplifying the fabrication processes and reducing the manufacturing cost for the shirt.

In addition, since the present invention employs the fabric core and/or the adhesive film having superior flexibility, the wearing comfort may be improved as compared with the prior art employing the plastic adhesive tape.

Furthermore, according to the present invention, each seam part of the shirt can be obtained by folding the adhesive tape, so that the adhesive characteristic of the seam part can be improved.
